async function listVoices(language = null, gender = null) {
  const params = new URLSearchParams();
  if (language) params.append("language", language);
  if (gender) params.append("gender", gender);

  const response = await fetch(
    `https://api.speechgen.com/v1/voices?${params}`,
    {
      headers: {
        Authorization: `Bearer ${process.env.SPEECHGEN_API_KEY}`,

import requests

def list_voices(language=None, gender=None):
    params = {}
    if language:
        params['language'] = language
    if gender:
        params['gender'] = gender

    response = requests.get(
        'https://api.speechgen.com/v1/voices',
        headers={
